An apparatus for shaping packaging material, comprising a housing support including hopper, a packaging material reservoir, a discharge orifice, and a bearing structure therebetween defining a continuous feeding path for the packaging material. The feeding path includes an interior wall continuously extending around an axis of the material's feeding direction. The housing support further includes at least one concavity in the bearing structure extending laterally away from the feeding path, the concavity having a portion within the feeding path at a slit formed within the interior wall, the concavity holding a shaping device that is rotatably mounted on the bearing structure and partially projects from the slit into the feeding path, the shape of the slit being complementary to the shape of a section of the shaping device adjoining the slit such that a tolerance gap is formed allowing the shaping device to rotate relative to the bearing structure.
